CHARLES 0. WILSON, OF QUINCY, ILLINOIS.

OIL-BURNER.

Specification of Letters Patent.

Patented Aug. 30, 1910.

Application filed May 26, 1910. Serial No. 563,675.

To all whom it may concern:

Be it known that I, CHARLES C. WILSON, a citizen of the United States residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Oil- Burners, of which the following is a specification.

This invention relates to oil burners, and has for its object to provide an improved device by means of which oil may be burned in a stove, range, or other heater, the burner being adapted to be placed in the ordinary fire pot of such stove or heater.

The invention embodies means for mixing steam and air with the oil to be burned, said mixing being effected in a casting or pan in which combustion takes place, which casting may be set in the fire pot referred to. The combination of heated oil, steam and air forms a gas in the fire pot which when burned will give an intense heat, and combustion is effected without the use of a separate retort or generator, and the device is of such simplicity that it can be readily placed in an ordinary fire pot without special construction or modification thereof.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a plan view of the device. Fig. 2 is a cross section of Fig. 1. Fig. 3 is a longitudinal section on the line 33 of Fig. 1.

Referring specifically to the drawings, 6 indicates a box or casting which may be of proper size and shape to fit within the fire pot of an ordinary stove, or it may be otherwise constructed according to local needs or conditions. This box is open at the top and closed at the bottom, and is provided with several rows of upright tubes 7 which form openings through the bottom and which proj ect upwardly within the box toward the top thereof. These tubes serve to admit air to the combustion chamber.

At one side of the box, some of the tubes inclose upright oil pipes 8 which extend through said tubes and are provided at the top with heads 9 which rest upon the tops of the tubes. These heads have jet holes 10 for spraying the oil, or the gas resulting therefrom, in various directions within the upper part of the box. The oil is supplied from a tank 11 by means of a pipe 12-, the flow being controlled by a valve 13. One or more of the oil spraying heads or tubes may be used.

Water is supplied from a tank 14 or otherwise through a pipe 15, provided with a valve 16, to a cylindrical water vessel 17, the pipe 15 conveniently extending up through one of the tubes 7. The vessel 17 is closed except for inlet and outlet, and extends along the side of the casting opposite to the oil spray heads 9. It is connected by a short pipe 18 to an upper steam drum or dome 19, which is a cylindrical vessel extending lengthwise above the vessel 17 and in slightly inclined position toward one end where it is connected to the vessel 17 by the pipe 18. The steam chamber 19 has a row of jet holes 20 along one side of the same, directed toward the heads 9.

In operating the burner it may be started by allowing some of the oil to flow into the bottom of the box 6, and igniting the same, or it may be ignited at the jet holes 10. The heat generates gas in the heads and the pipes leading thereto, air being supplied through the tubes 7. When sufliciently heated steam will be generated in the vessels 17 and 19 and will be discharged through the spray holes 20 toward the oil or gas spray issuing from the holes 10. The oil, steam and air will thus be mixed in the fire box and will burn with a blue flame, without smoke or odor. Crude oil may be used in the device, and as stated it can be very readily attached to an ordinary stove by setting the box 6 in the fire pot, upon the grate bars, and making the necessary pipe connections for the oil and water supply. The heat generated in the box produces a continuous supply of oil vapor and steam, the steam being heated to a high degree in the upper vessel 19.

Various modifications may be made in the shape, size and arrangement of the various parts, and no limitation in this respect is implied.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. An oil burner comprising a box open at the top and having a series of air tubes projecting upwardly into the same and above the bottom thereof, an oil spray device lo cated in the box and arranged to discharge oil above the upper ends of said tubes, and a steam spray device located in the box and having jet openings above the upper ends of said tubes, and arranged to mix steam with the oil spray, in said box.

2. An oil burner, comprising a box having a bottom and sides and open at the top, a series of air-supply tubes projecting upwardly into said box, said tubes being of less height than the sides of the box, an oil spray device located at one side of the box and discharging over said tubes, and a steam spray device located at the other side of the box and discharging over said tubes, to mix the oil, air and steam in the space above said tubes.

3. An oil burner comprising a box having air supply openings in the bottom thereof, an oil spray device in the box, arranged to discharge over said openings, and a steam spray device in the box, consisting of a lower vessel connected to a Water supply, and an upper vessel connected to said lower vessel and having spray holes arranged to discharge over said openings.

In testimony whereof, I aflix my signature in presence of two Witnesses.

CHARLES C. WILSON.
